If you cut a center on a piece and then move it off center wouldn't the center be moving in a orbital pattern not rotating around it's axis as such wouldn't it...
True, but I wanted to make it clear there are a lot of options out there for turning tapers without offseting the tail stock. I told up front you cannot chuck...
True, and sometimes inconvenient. This is why I like using my criterian type boring head with a center in it for tapering. It just makes life so much easier to...
Bill Before I shifted to using the criterian boring head to offset things at the tailstock end the small end was at the headstock end of the part which made...
... In the beginning yes, but after cutting off all the stuff not on the drawing the part will present to the cutter a smooth cutting surface that when removed...
... Cutting a taper with one end held in a chuck and the tailstock end held by a center- with either end offset, is asking for trouble. The work cannot be held...
Tapers and balls are two things that I plan to do often on my new lathe. I can see how the boring head can be used to turn tapers, but how can it be used for...

Ivy, At first glance I would agree with you but after thinking about it it is possible. The center axis of the tapered part will not be parallel to the...
When you cut a crankshaft or cam on a lathe its the work its self that is off centered, ( one set of 2 center holes are bored off center) not the live and dead...
how about turning up a 60 degree center with a straight shank and offsetting that in the four jaw chuck and using a dog to drive the work between centers. That...
HI David If the tailstock is concentric with the headstock the tool in the toolholder is going to cut a parelell to the center line of the lathe. That is all...

Van That is how I did it for years until I started using the boring head in the tailstock instead, JWE Long Beach, CA ... From: " Dogwood Ridge (Peoples)"...
And that is the same way when you setup a taper using either a tailstock setover or a headstock setover. This can be done at the tailstock either by offsetting...
As a owner of Unimat I’m well aware of how you can turn the head stock to make a taper, but thats a long way and a whole different thing than the stuff you ...
Hi JW, correct me if I am wrong, but if I remember correctly, wasn't the advantage of the Unimat that you could actually set the headstock so that the spindle...
Parts of this may show up twice (or not) There is an essential difference between offsetting the tail stock, and offsetting a center in the 4 jaw. When...
THe files I mentioned are in files, under "headstock offset taper turning " And easier way of explaing what I was saying, is to note that if the axis of...
Frank The Unimat method is much better than using the 4 jaw to offset, but for early machines like the original 7x10 lathes that have no way to offset the...
